Hey guys, 19M my current credit score is over 700, across all three credit bureaus. Opened my first credit card at 18 then after turning 19 I opened three new credit cards in 6 months, I always make on-time payments, and keeping my credit utilization under 10%, my total credit limit $2,100. Is there any advice or tips I should implement to improve my score over the next couple of years?
